To all whom, it mctyconcczjn:

Be it known that I, CAMILLE AMEYE, a citi-'V zen of the'Kingdom of Belgium, residing at' Iseghem, Belgium, have invented certain newy and usefnllmprovements in Processes ofand Apparatus for Sterilizing and Satu rating with Carbonio Acid Gas Liquids Oontainedin Casks or Like Vessels; and I do hereby declare the following to be a full, clear, and eX-. act description of-the invention, such as will enable others skilled in the art to Which itv appertains to make and use the saine, .referencebeing had to the accompanying drawings,

f of a storage or dispensing vessel may be ster,-v ilized or sterilized and carbonated; and oneof the essential features of invention consists in a coil of pipe constructed for introduction into such vessel through the filling-aperture thereof, so that a heating agent may rst he passed through such coil to heat the contents of the vessel to a sterilizing temperature, and so that after the completion of this operation a cooling agent may be passed through said coil to cool the contents of the vessel, after which said contents may be carbonated.

A further object of my invention lies in the connection of a coil of pipe such as above referred to with inlet and 'outlet passages in a stopper for the-iilling-aperture of the vessel,in means for passing a heating agent or a cooling agent at will through said stopper and coil, and in means for moving the vessel and therethrough keeping its contents in motion t'o expedite the heating or the cooling and to keep the contents (especially when malt liq uors are treated) from acquiring a burned taste, which would be the case if the liquor were quiescent.

The invention has for its further object the provision of means for passing a heatingor a cooling agent at will through the aforementioned coil and stopper and the provision of means for passing'air or carbonio-acid gas through the stopper after the heating and subsequent cooling of the contents of the vessel.

l -Theinvention has forits further object the provision of means for'collecting gases evolved from `theliquid treated and educting the same to-avoid overpressnres, to include a gasrcollector and a pressure-reducerin the air or gas circuit, the reducer discharging intoV the collector, and the latter communicating directly with the interior of the vessel through the aforementioned stopper; to provide,v means for educting the gas collecting in said collector during the heating of a liquid to be treated, so that said collector will act as an expansion chamber during the aerating or carbonating operation to further reduce the jpressure ofthe air or gas, and to combine vwith the appliances means for moving the vessel'containing the liquid to be treated, so

as to keep its contents in motion during the three operations of heating, cooling, and aerating or carbonating.

The invention has for its further object a revoluble shafta maincircuit for a' heating Vand a cooling agent having itsinlet and outlet through said shaft and including the aforementioned stopper and coil, a branch circuit for air or gas having its outlet through said stopper and including the aforesaid gascollect-or and pressurereducer, means for passing aheating or a cooling agent at will through the main` circuit, means for cutting off the communication between the stopper and its coil and the inlet to the main circuit and for establishing communication between said inlet and the branch circuit, means for vpassing air or gas through said branch circuit, and means for supporting a vessel or vesapparatus, the supporting-framework being' only partly shown. Fig. `2 is a section taken on line A B of Fig. 1. on line C D of Fig. 2.

View of the apparatus.

Fig. e is a top plan Fig. 5 is a like view Fig' is a section takenV IOC of the pressure-regulator. on the line E F of Fig. 5, and Fig. 7 is'an elevation of one of the clamping-plates.

In bearings 2 on standards 1 of a suitable framework is mounted a shaft 3, which carries a fast and a loose pulley 4 and 5, respectively, said shaft having two passages 3 and 3b formed therein and extending from its ends toward its longitudinal center. To the passage 3IL is connected fluid-tighta supply-pipe 6, supported from an arm 1, projecting from one of the frame-standards 1, the connection being a Well-known one and such as to allow the shaft to revolve freely on said pipe G, which has three branches 6, Gb, and 6", respectively, each provided with a stop-cock. The branch G is for connection with a suitable source of hot-water or steam supply, according as one or the other is used as a means for heating the contents of a holder or holders to a sterilizing temperature, the branch 6b for connection with a suitable source of refrigerant-supply, as cold water, and the branch Gc for connection with a suitable source of carbonic-acid-gas supply.

To the passage 3* in shaft 3 is connected fluid-tight an exhaust-pipe 7, supported from an arm 1b, projecting from another standard 1 of the main frame, the connection of said exhaust-pipe being also well known and such as to allow shaft 3 to revolve freely on said pipe 7, which has two branches 7a and 7b, each provided -with a stop-cock, the branch 7n serving for the discharge of condensed steam or hot Water and for the discharge of the refrigerant and the pipe 7b for the escape of gas.

The apparatus shown in the drawings is constructed to receive and support two barrels 8 S, the su pporting appliances being constructed and arranged as follows: A baseplate 9 is bolted to a two-part standard 10, each of said parts having a semicircular recess lOfL, forming a bearingfor the shaft 3, and each of said halves has two arms 10" projecting laterally therefrom, said arms having each averticalslot 10U. Thetwohalvesofthestandard are bolted together below and above the shaft-bearing, so as to rigidly connect said standard with the shaft and cause it to revolve therewith. The base-plate 9 has internally-threaded sleeves, in which work screws 11, acting on skids or supporting-platforms 12, provided with concave seats 'for the barrels 8 and 8, and to said base-plate 9 are secured arms carrying hooks 9 for chains 13, there being two such chains for each barrel. It is obvious that when the chains are passed around a barrel near its opposite ends and hooked to hooks 9a on the base-plate and the tightening-screws 11 are rotated in the proper direction the skids 12 force the barrels against the chains, thus firmly securing said barrels nea-r both ends. To further secure said barrels to their support, I provide clamping devices, which consist of head-plates 14g, each having two radial arms 14, on which .poses presently to be described.

Fig. (i isa section l arc mounted shoes 14", so as to Slide thereon. The upper face of these shoes is convex and beveled to fit against the barrel-heads and the ends of the barrel-staves, and by mounting them so as to slide on the radial arms of the plates 14C barrels of different sizes can be clamped to .the described supporting devices. These plates 14 are clamped to the barrel-heads on the one hand by means of the slotted diverging arms 10b on the two-part bracket-standard 10, against which bear the plates 14, applied to the proximate heads of the two barrels, and on the other by means of clamping-plates 15, applied to the plates 14 on the outer heads of said barrels and clamping-screws 16, acting on said plates 15 and working in a cross head 17, carrying headed rods 18 at its opposite ends, which rods extend through the slots 10c in the diverging arms 10b of the bracket-standard l0. Itis obvious that 'when the clamping-screws 1U are rotated in the proper direction the crosshead 17 is drawn away from the barrel, while the arms 10b in bracket-standard 10 and the clamping-plates 15 are moved toward each other, thus clamping the barrel firmly, so that in conjunction with the chain-fastenings above described the barrels 8 and 8 are firmly connected with the bracket-standard, and as the latter is rigidlyA secured to the shaft 3 said barrels will revolve therewith when power is applied to the fast pulley 4.

The shaft 3 carries a radially-arranged pipe 13, that communicates with the passage 3"L in said shaft, and is provided with a two-way cock 1S, said pipe having a branch 18h for purposes which will be presently described. A similar pipe 19 communicates with the passage 3b of shaft 3and is provided witha twoway cock 19, having a branch 191 for pur- The outer end of pipe 1S has two branches for flexible pipes 21 and 21, connected 'with the inlet `branch of pressure-regulators 20, whose said inlet branches are provided with stop-cocks 23 and 24. That portion of the pipe 18 above its stop-cock 1Sn is removable, so that the removable section 18c can be shifted from said pipe 1S and connected with the pipe 19, Fig. 3, for purposes presently to be described.

The pressure reducer or regulator 20, Figs. 5 and consists of acomparatively shallow circular casing divided horizontally into two chambers 25 26 by a partition 20, and said chambers are placed in communication with each other through ports in the circular wall of the casing and through curled or coiled pipes 2Ob of very small internal cross-sectional area, whereby the stream of carbonicacid gas under pressure flowing` into receiving-chamber 25 is not only divided, but its speed of flow, and hence the pressure under which the gas flows into the delivery-chain ber 26 is materially reduced. This pressure is further reduced as the gas passes from the pressure-reducer into the gas-collector, which IIO ISO

in the carbonatihgof the gas acts as an expansion-chamber, as will be readily understood.

The delivery-chamber 26 of the pressurereducers is connected with a gas-chamber 27, which carries a bung which is preferably detachably secured thereto.V These bungs 34 and 35 have a through-passage 28 and separate inlet and outlet passages and branches. The inlet branch of one of the bungs 34 closing bung-hole of barrel 8 is connected by a flexible pipe 29 with the branch 18", Fig. l, of pipe 18, and the outlet branch of said bung is connected by a dekible pipe 30, Fig. 2, with the inlet branch or bung 35 closing bung-hole of barrel 3, the outlet branch of which bung 35 is connected by a flexible pipe 31 with the branch 19a of pipe 19, the circuit from pipe 18 to pipe 19 being completed by pipes 32 and 33, coiled into a corkscrew shape, the terminals of pipe 32 being secured to bung 34 to connect its inlet and outlet passages, respectively, and the terminals of the pipe 33 are simil'arly connected to bung 35, so that in applying said bun gs to their bung-holes the said pipes will be Wholly within their respective barrels.'

The object in ceiling the pipes 32 and 33 in the form of a corkscrew is to secure as extensivea superficial area as possible with a limited cross-sectional area of the coil and also to admit of the coils being screwed into the barrels through the bung-holes.

The operation of the apparatus is as follows: A couple of barrels, the contents of which are to be sterilized or sterilized and carbonated, are secured to the skids 12 bythe means hereinabove described, the corkscrew pipes 32 33 being inserted into the barrels and the bung-holes thereof tightly closed by means of the `bungs 34 and 35. The stopcocks 23 and 24 in the connection between pipe 18 18c and the pressure-reducers 2O are closed, the stop-cock 182l set to establishscommunication between pipe 18 and iiexible pipe 29, and the stop-cock 19 in pipe 19 set to establish communication between said pipe 19 and flexible pipe 31. A circuit is thus established from passage 3 in shaft 3 through pipe 18, corkscrew pipes 32 33, pipe 19, and pas- K sage 3b in said shaft 3, and by opening the stop-cock in branch 71 of exhaust-pipe 7 and stop-cock in branch 6 of feedpipe 6 hot Water or steam will dow through the described circuit and escape through-branch 7b, thereby heating the contents of the barrels.

The operation of heating can be materially expedited by revolving the shaft 3 and the 'barrels so as to continuously displace the contents of the latter about the pipes 32 and 33. In this manner the contents of the barrels are heated to a sterilizing temperature and maintained at such temperature for any required length of time.

lVhen liquids evolving gases at a sterilizing temperature are treated, such gases collect in the gas-chambers 27, and in orderto avoid excessive pressures the rotation of the shaft 3 may from time to time be stopped when the pipes 18 and 19 are in a vertical position. The supply of heating agent is then temporarily cut ed, the stop-cock in branch 71l of exhaust-pipe 7 closed, and the stop-cock in the branch -7h of said pipe opened, While the stop-cock 19 is set to cut off communication with pipe 31 and establish communication with its branch 19h. If now the removable section-'13e is disconnected from pipe 18 and connected with pipe 19, as shown'in Fig. 1, and the stop-cocks 23 and 24 opened, the gas in the gas-chambers 27 and the pressurereducers 20 can be exhausted through exthe sterilizing temperature to or about to atmospherictemperature and it is desired to carbonate said contents, the stop-cock in branch 6b, Fig. 3, of supply-pipe 6 is closed, the stop-cock in pipe 18 so set as to cut off the communication with pipe 29, Fig. 2, and establish communication with pipes 21 and 21,, the pressure-reducers 20, and through the gas-chambers 27 and the bungs with the interior of the barrels 8 and 8a, the stop-cocks 23 and 24 being open, while the stop-cock 19 of`pipe 19 may or may not be closed, since the stop-cock 18 when set as described cuts the heating. and cooling circuit out of the gassupply circuit. The stop-cock in branch 6 -may nowbe opened and carbonic-acid gas under sufficient pressure admitted to the barrels until their contents are charged or saturated with gas, when the supply of the latter is cut oft', the pressure reducers and gas- Achambers and bungs 34 and 35 are removed from the barrels, and the latter bunged up in the usual manner and finally removed from their supports. f

It will of course be readily' understood that the carbonation of the contents of thebarreis may be materially expedited by revolving the barrels and that instead of carbonating the liquid it may be sim ply aerated by connecting the branch Gc with a source of supply of sterilized air under pressure.

To those conversant with the art of sterilizing liquids, and particularly malt liquids, the apparatus described presents a great advantage over those hitherto used-namely, in that a special sterilizer is dispensed with and in that the burned taste imparted to malt liquids 'sterilized by means of a heating-coil surrounded by the liquid in a stationary sterilizer is avoided, because the liquid in the apparatus described is continuously displaced or kept in motion about the circulating-coils IOO IIO

by revolving the barrels about a common axis and in that a special carbonating apparatus and the agitating devices commonly used are also dispensed with.

The apparatus has the further advantage of accom modatin g barrels of different capaci- Having thus described myinvention, what I claim as new therein, and desire to secure by Letters Patent, is
